Using HP-IB or HP-IL Interface Model 1630A/D/G
TS - Transmit State Acquisition Learn String
The transmit state acquisition learn string command causes the HP 1630G analyzer to transmit a string
containing its state measurement data plus two CRC bytes. The measurement data consists of state trace data,
state label overview data, time interval overview data, time positional data, or linkage overview data.
The actual state data (trace, label overview, time interval, time positional, or linkage overview) istransmitted in
the following manner . The first seven bits of the MSB are internal . The last two least significant bits of the MSB
correspond to data from Pod 7 bit 9, etc ., as shown below .

Note
The binary value of these bytes is the number of bytes to follow including the
CRC bytes. This value is transmitted as MSB first and LSB last. The maximum
number of bytes that can be transmitted is 5689 for 57 channels and 6204 for 65
channels .
